The Boston Fire Department reports firefighters responded to the Tobin Bridge around 11 p.m. on Monday for a fire in the shaft that used to carry toll takers up to and down from the bridge's toll booths from Terminal Street in Charlestown.

Some plastic about halfway between the ground and the lower deck caught on fire in the shaft, which is in the process of being demolished, the department reports. There were no injuries in the two-alarm fire, but outbound traffic was delayed.

UPDATE: 9:07 p.m. Negotiators succeeded in talking him down and he's now in police custody.

The Tobin Bridge is shut to inbound traffic as Boston and State Police negotiators try to convince a man who climbed the girders up to the top to come down. Just in case, the Coast Guard and the Boston Fire Department have personnel stationed on and near the Mystic River.

State Police investigating an abandoned motor vehicle on the Tobin Bridge at about 6:40 this morning observed the body of its apparent owner on a Charlestown street below the bridge. A death investigation is now under way by State Police detectives and other specialized units. The evidence does not currently suggest foul play.

The Suffolk County District Attorney's office reports on an incident shortly before 7:30 p.m.:

State Police detectives assigned to the Suffolk DA's office, along with uniformed troopers and specialized State Police units, are on the upper deck of the Tobin Bridge and on the street below in Charlestown for a death investigation involving an adult who left a motor vehicle and went over the rail. The preliminary evidence does not suggest foul play, but the investigation is still in its early stages.

Chelsea Police report Officer Paul McCarthy received an award for saving the life of Mostafa Laassal, who, allegedly, on being pursued by police after stabbing his wife, jumped off the top level of the Tobin Bridge, only to be snared in safety netting installed for workers on the bridge repainting project:

Traffic across the Tobin Bridge came to a halt around 10 a.m. when a man being pursued by Chelsea Police jumped out of a livery car, went to the side of the bridge and jumped.

Ted Pendergast reports he got caught in safety netting set up for the bridge repainting project. He'd brought a knife with him and tried cutting through the netting, but first responders managed to get to him before he could. They "packaged" him and put him in an ambulance for transport to a nearby hospital.

A T bus (maybe a 111) died on its way across the Tobin shortly after 7 a.m., forcing its riders to transfer to a 426 bus in mid-span - some 254 feet above the Mystic River. A.P. Blake, who shot the video, reports:

We're about to transfer passengers from one bus to another... IN THE MIDDLE OF THE TOBIN!

The state begins its new toll-plaza-less tolling system on the Tobin tomorrow. Drivers with EZ-Pass transponders will have $2.50 added to their bill for every inbound trip. Drivers without the transponders will have their license plates photographed and scanned and a bill for $3 will go to the registered owner of the vehicle for each trip.

State Police say they've identified a Chelsea man as the person who caused a crash that injured five people on the Tobin Bridge around 11:30 a.m. and that once they find him will charge him with a variety of offenses, including speeding and leaving the scene of an accident.

State Police say the Corolla driver, 38, ran down the ramp from the lower deck into Chelsea, leaving his passenger, a 38-year-old woman from Roxbury, to fend for herself.
